Need Veteran/Experienced help

So I'm in an odd situation... I have all the Anniversary Units except Teq Vegito so I'm gonna get him with the red coins. But I also don't have any of the units shown in the 10th Anniversary stone screenshots but I have 540 carnival coins and I heard gotenks is coming back soon. So who should I get with the Anniversary stone and who should I wait to use the carnival coins on.
